Easy to read and understand. Pictures are just ok.

Big Display and easy to use

I run the HDS 7 in my RZR.
Great size, easy to see in hight sun light.
Easy to use.
I log all my trails and capture all the cool points.
If it is in your budget.... "No min. $$$ for the right stuff".
This is a must have.
I also use mine on my boat and brought a seperat mount and cable for arount $50 bucks. It works great on the water too..
In the dirt it is great not to have a touch screen. It would get all scratched up.
I mounted mine on the right side off dash, behind steering wheel. Perfect for me "the driver"; however passanger can't see it very well.
